Differential postnatal development of mu and delta opiate receptors
Brain Research
|April 1, 1982
Abstract:
We found a differential postnatal development of mu and delta opiate receptors. Mu receptors labelled with low concentrations of [3H]naloxone appeared to develop earlier than did delta receptors labelled with [3H]D-Ala2-D-Leu5-enkephalin (0.5 nM). Competition binding studies also revealed a delayed appearance of delta receptors (day 12 postnatal).
